The rgmanager package. All users are advised to use Pacemaker for their failover needs.

The openais package. This provided some of the SA Forum AIS APIs, which were rarely used.

The heartbeat package. Upstream development has stopped and equivalent or superior functionality is provided by the Corosync package.

The piranha package. Superior functionality is provided by the Keepalived package.

The ricci package. Similar agent-style communication can be provided by Matahari or other projects.

The luci package. This will be replaced by Sunzi, although it is not clear this part will make Fedora 17.

The clustermon package. This was part of the ricci/luci administration stack and is no longer required.

Several agents in the resource-agents package which previously relied on examination of cluster.conf at run-time.

Benefit to Fedora

The increased reliability and versatility of the cluster components included in Fedora 17 allow administrators to deploy Fedora in environments where greater availability and clustered file systems are required.
Removal of rgmanager matches the capabilities offered by several other Linux distributions and allows the Fedora community to consort efforts on a single failover stack.

Scope

This change impacts several utilities and other applications, including:

The DLM, which used AIS Checkpoints to replicate data about POSIX locks (100% complete)

Clustered LVM, which used CMAN APIs, will need to be ported to corosync. (?% complete)

Fence-virt, which used CMAN APIs and AIS Checkpoints, will need to be ported to corosync. (0% complete)

Pacemaker, which used CMAN APIs, will need to be ported to corosync (100% complete)

Clustered mirroring, which uses AIS Checkpoints will need to be ported to corosync (?% complete)

QPid, which used CMAN APIs, will need to be ported to corosync (?% complete)
